LIFTING-PUMP.

SPECIFICATION forming part of Letters Patent No. 292,1C5, dated January 15, 1684;.

Application filed March 31, 18:73. (No model.)

To all whom, may concern:

Be it known that we, CYRUs lI. CURTIS and J mns E. Grunn, citizens of the United States, residing at Logan city, in the county of Cache and Territory of Utah, have invented a new and useful Lifting-Pump, of which-the following is a specification, reference being had to the accompanying drawings.

This invention relates to pumps, and more especially to that class which have a lifting action 5 and it consists in certain improvements in the construction of the same, as will be hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawings, Figure lV represents a vertical longitudinal section of a pump equipped with our improvements. Fig. 2 represents a sectional view of the plunger on the line x x, Fig. l, but on an enlarged scale. Fig. 3 represents a perspective view-of the sanie.

The same letters refer to corresponding parts in all the iigures. n

Referring to the drawings, A designates the pump-barrel, having cast thereon a suitable base and legs for its support in the well. Said barrel is provided with an inlet-passage, c, and around said passage the valve-seatis beveled, to conform to the outer surface of a checkvalve, B, wor-king in said passage. Connected to the bottom of said valve is a rod, C, working in an opening, c, in the angular crossplate D, and provided with a head, d, iitting over said opening, and serving to limit the upward movement of the check-valve. Guide plates or rods b are secured to or formed with the said valve B, and these plates serve to guide the valve to the proper position in its upward and downward movements.

E is a sucker-rod attached to the upper part of plunger E, and working in a passage, E', at the top of barrel A. The said plunger is formed in two parts, ff', the upper part, f, being constructed of a series of arms, g, secured to a ring or annulus, h, which is internally screw-threaded, to receive the screwthreaded end ot' part f. A valve, G, works in an opening, i, of said part f, and is provided with guide plates or rods j on its under side, serving to guide the valve G when 5o upper part of plunger F prevent the displace- 6o ment ofthe valve G when the latter is pushed upward, and they also serve as guides for the said valve. Grooves 'm are formed in the eircumference of both the upper and lower parts of the plunger, and a water-packing is thus 65 formed, thereby obviating the objections to ordinary piston packing. rlhe top of the pump-barrel is removable, as will be seen.

The pump may be of any size required, and

the plunger may be reciprocated by hand, 7o

steam, or other power, as desired.

The operation of our pump is obvious. On the upstroke of the plunger', water enters the pump-barrel through the valve B, and on the downstroke water enters the plunger through 7 5 the valve G, permitting` that part of the barrel above said valve to become iilled with water. As the plunger begins to ascend, the valve G closes and the water is forced out through a suitable discharge-spout. not confine ourselves to any particular arrangement of spout, so we have omitted this from the drawings, preferring to leave to the option and discretion of the maker.

Our improvements are applicable to both 85 single and double acting pumps.

Having described our invention, what we claim is In a pump, the combination, with the pumpbarrel, of the plunger F, formed in two parts, 9o
